The Cat's Eye Nebula from Hubble
Explanation:
Staring across interstellar space, the
alluring Cat's Eye
nebula lies three thousand light-years from Earth.
A classic
planetary
nebula
, the Cat's Eye (NGC 6543) represents
a final, brief
yet
glorious phase
in the life of a sun-like star.
This nebula's dying central star may have produced the simple,
outer pattern of dusty
concentric shells
by
shrugging
off
outer layers
in a series of regular convulsions.
But the formation of the beautiful, more complex
inner structures is
not well understood
.
Seen so clearly in
this sharp Hubble
Space
Telescope image,
the truly cosmic eye is over half a light-year across.
Of course,
gazing into the Cat's Eye
,
astronomers may well be seeing
the fate of our sun, destined to enter its own
planetary nebula phase
of
evolution ... in about
5 billion years
.
